    Abstract: Described is a packaging for liquid, made of cardboard, which is made impermeable to liquid by means of a plastic coating over its surface. It has side-walls, base and top wall (5), connected to one another by folded and/or sealed seams. A pouring aperture is located in top wall (5) close to the edge line, and can be torn off and has a separate plastic strip (8) covering the pouring aperture and being applied round the edge of the pouring aperture, and is sealed on at least from the inside.So that the edge of the pouring aperture remains covered with a protective layer after opening and so that the closure and the protective layer can be produced with simple means, according to the invention the plastic strip (8) covers the pouring aperture tightly and is fixed via two tacked strips (7, 31) to an outer cover strip, in which a hole (15) is located above the pouring aperture, the two tacked strips being smaller than the surface area of cover strip (6), the first tacked strip (7) being applied at a distance from hole (15) and outside the pouring aperture, the second tacked strip (31) being applied outside hole (15) of cover strip (6) and within the pouring aperture (16), the outer cover strip (6) being fixed to the top wall (5) of the packaging via a third tacked strip (9) lying outside the plastic strip (8).

    Abstract: A flattened tube of continuous film is opened up by being fed over a mandrel which is floatingly disposed within the tube. As the tube is passing over the mandrel, which serves as a backing, a layer of reinforcing tapes is helically wound thereabout and fixed thereto, whereafter the tube is flattened again. Each side of the tube is then successively provided with a layer of parallel further reinforcing tapes which are anchored by a plastics covering layer that is extruded thereon and pressed thereto.
